ROAD-ROLLER.

Application filed December 17, 1915.

To all whom it may concern.

Be it known that I, F ITOH H. BEACH, a citizen of the United States, residing at Charlotte, in the county of Eaton and State of Michigan, have invented a new and useful Road-Roller, of which the following is a specification.

The present invention appertains to road rollers, and aims to provide a novel and improved device of that character.'

It is the object of the invention to pro vide a roller adapted especially for use in road construction, the roller being so con structed as to effectively tamp the material from the bottom upwardly.

The roller comprises a plurality of independently rotatable sections having lugs projecting peripheries, tively tamp the material underneath the roller, and said lugs are so formed as to prevent the clogging or loading up of the roller. The weight of the machine is imposed upon the lowermost lugs, whereby said lugs will exert considerable pressure upon the material for compressing or tamping it, and the lugs are so formed as to prevent clogging, and to allow any stones or other objects which are forced between the sections to pass out without the liability of the stones accumulating within and loading up the roller.

It is also within the scope of the inven tion to provide a roller having the characteristics above noted, and which, at the same time, is comparatively simple and in expensive in construction and manufacture, as well as being thoroughly practical, serviceable and efficient in use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein- Figure 1 is a perspective view of the improved roller, a portion of the tongue being broken away. Fig. 2 is an enlarged cross section of the roller, illustrating the face of Specification of Letters Patent.

one section and lugs projecting therefrom. Fig. 3 is an enlarged fragmental detail of one section of the roller.

The roller proper is designated generally by the numeral 1, and said roller carries a rectangular frame 2 having a seat 3 for the operator. A forwardly projecting tongue 4: is attached to the frame 2 for enabling the roller to be drawn over the ground or road by draft animals, hounds or braces 5 connecting the tongue t and frame 2. Attached to the ends of the frame 2 are V-shaped brackets 6 having journaled to the crotch portions thereof a transverse shaft 7 upon which the roller 1 is mounted between the brackets 6.

The gist of the invention resides in the construction of the roller 1. This roller comprises a plurality of parallel inclependent sections, each embodying a disk 8 having a hub 9 which is mounted upon the shaft 7, the disks being rotatable inclependently of one another in order that the roller can be readily turned around or to one side or the other, without creating a draggingaction at one end of the roller or the other, as is the case with a solid roller. When the roller is pulled straight ahead, the frictional engagement of all of the hubs 9 with the shaft 7 will naturally rotate the shaft 7 with the disks, but the disks can rotate upon the shaft 7 when the roller is angled upon the ground or road. Each disk 8 has upon one of its faces only, an annular series of outstanding lugs 10 adjacent the periphery thereof, said lugs being arranged relatively close together radially of the disk. The lugs 10 project from one side or face of the disk, while the opposite side or face of the disk is plain. The lugs are triangular in contour, and have their outer edges flush with the periphery of the disk and the cylindrical surface of the roller. Said lugs are also tapered from their basal or butt ends to their tips, whereby the slots between the lugs increase in width from the disks to the open ends of said slots. The disks or sections are also spaced apart sufliciently, that the slot between each set of lugs 10 and the adjacent section or disk is greater in width than the slots between The disks 8 may or may not be provided with openings 11 between the hubs 9 and lugs 10.

In operation, when the roller is drawn over the gravel or stone during the construction of a road, the lugs will penetrate said gravel or material, since said material is loose, and the lugs will therefore tamp the material at the bottom first, and as the roller is moved back and forth, the material will be compacted from the bottom to the surface, whereby the entire mass will be thoroughly tamped or compressed, and in a manner which is far superior to the mere oompressing of the material from the top as is done by an ordinary roller. Thus, as the gravel, stone or other material 1s rolled, the

V roller will first pack the material at the bottom, and as the material becomes packed, the roller will rise to'the surface still continuing the tamping action. Since the weight of the machine is imposed upon the lowermost lugs, said legs will thoroughly compress the material.

The present roller can also be'used to advantage for cutting up the sod during the grading of the road, since the weight of the H the gravel and stone to readily fall out.

This prevents stone and gravel from accumulating within the roller. The tapering of the lugs prevents the stone and gravel from lodging between the lugs, so that the roller will not become clogged.

The lugs of the sections or disks at the opposite sides of the center of the roller project inwardly, that is, the lugs of each set of sections project in the same direction toward the center of the roller. The lugs of the two innermost sections project toward one another, whilethe lugs of the other sections project toward the plain faces of the coinpanion sections which is desirable in that the stone and gravel which passes between the lugs will-be directed towardthe plain faces of the adjacent sections, whereby said stone and gravel can readily pass out. 7

Having thus described the invention, what is claimed as new is i r V V 1. Aroller embodying disks each having an annular series of lugs projecting from one face thereof flush withits periphery,

the other faces of the disks being plain, and

the lugs projecting in the same direction toward the plain faces of the companion disks, the slots between the lugs and companion disks being wider than the slots between the lugs.

provided with annular series of triangular lugs projecting from certain faces thereof, the outer edges of said lugs being flush with the peripheries of said disks, and the lugs being tapered from their butt endsto their tips, the other faces of the disks being plain, the lugs projecting in the same direction toward the plain faces of the companiondisks,

2. A roller embodying a plurality of disks 7 the lugs being arranged close together and 7 having slots therebetween increasing 1n width from the IGSPQCtUOCl'lSliS, and the" slots between the lugs andcempanion disks being wider than the slots between the lugs.

In testimony that I claim the foregoing as my own, I have hereto aliixed my signature in the presence of two witnesses.
